EU AI Act for U.S. SaaS and GenAI companies
A U.S. SaaS vendor can face different AI Act obligations depending on whether it provides an AI system, provides a GPAI model, deploys a third-party system or integrates AI into a regulated use case.
Updated and legally reviewed: 29 September 2026.
Direct answer
Start by separating the application layer from the underlying model.
Using a third-party foundation model does not automatically make a SaaS company the GPAI model provider. The SaaS product can nevertheless be an AI system for which the company has provider obligations, depending on the facts.
Application provider
Map your own-name product, intended purpose, EU market placement and downstream customer use.
Model provider
If you actually develop and provide a GPAI model, Articles 53–55 and non-EU representative questions require separate analysis.
Generative features
Article 50 can create transparency or technical marking obligations depending on the function and actor role.
Customer use case
An application used in employment, credit or another listed Annex III use case can require high-risk classification analysis.
Contract architecture
Vendor labels do not settle AI Act roles.
Document the model supplier, system provider, deployer, intended purpose, modifications, branding and EU distribution chain. Reassess when those facts change.
Free screening tool
Start with classification, not assumptions.
Use the relevant EU AI Act checker to identify scope, role and classification questions before building the compliance plan.
